“Wherefore thus saith the Lord, Every alien son is uncircumcised in heart, and uncircumcised in flesh” (that is, unclean in body and soul): “there shall not enter one of the strangers into the midst of the house of Israel, but the Levites.”[667] He calls those that would not believe, but would disbelieve, strangers. Only those who live purely being true priests of God. Wherefore, of all the circumcised tribes, those anointed to be high priests, and kings, and prophets, were reckoned more holy. Whence He commands them not to touch dead bodies, or approach the dead; not that the body was polluted, but that sin and disobedience were incarnate, and embodied, and dead, and therefore abominable. It was only, then, when a father and mother, a son and daughter died, that the priest was allowed to enter, because these were related only by flesh and seed, to whom the priest was indebted for the immediate cause of his entrance into life. And they purify themselves seven days, the period in which Creation was consummated. For on the seventh day the rest is celebrated; and on the eighth he brings a propitiation, as is written in Ezekiel, according to which propitiation the promise is to be received.[668] And the perfect propitiation, I take it, is that propitious faith in the gospel which is by the law and the prophets, and the purity which shows itself in universal obedience, with the abandonment of the things of the world; in order to that grateful surrender of the tabernacle, which results from the enjoyment of the soul. Whether, then, the time be that which through the seven periods enumerated returns to the chiefest rest,[669] or the seven heavens, which some reckon one above the other; or whether also the fixed sphere which borders on the intellectual world be called the eighth, the expression denotes that the Gnostic ought to rise out of the sphere of creation and of sin. After these seven days, sacrifices are offered for sins. For there is still fear of change, and it touches the seventh circle. The righteous Job says: “Naked came I out of my mother’s womb, and naked shall I return there;”[670] not naked of possessions, for that were a trivial and common thing; but, as a just man, he departs naked of evil and sin, and of the unsightly shape which follows those who have led bad lives. For this was what was said, “Unless ye be converted, and become as children,”[671] pure in flesh, holy in soul by abstinence from evil deeds; showing that He would have us to be such as also He generated us from our mother--the water.[672] For the intent of one generation succeeding another is to immortalize by progress. “But the lamp of the wicked shall be put out.”[673] That purity in body and soul which the Gnostic partakes of, the all-wise Moses indicated, by employing repetition in describing the incorruptibility of body and of soul in the person of Rebecca, thus: “Now the virgin was fair, and man had not known her.”[674]
